Overview

This project has been defined for a vacation research student who is interested in earthquake-strengthening studies.

A large number of older low ductile reinforced concrete and/or masonry buildings exist in Brisbane City and Australia. These types of buildings have a demonstrated poor performance in earthquakes. One way to strengthen the buildings is the use of Fibre-reinforced polymers (FRP). Although a lot of research has been conducted in this area, they mostly focus on a strength criteria. This study has been proposed to investigate performance criteria other than strength achievement, e.g. the usability of the building after the earthquake, etc.

This project has been defined as a starting point to develop performance-based seismic strengthening of buildings. It is offered for all levels of study including Vacation Research Students, Honours, Masters, or PhD study.

Research activities

The Vacation Research Students can expect to undertake some or all of the activities below:

  • literature review of FRP strengthening of concrete and masonry buildings targeted to specific building performance levels
  • desktop analysis and data interpretation
  • limited numerical analysis

In addition to the above activities, Masters or PhD applicants can also expect:

  • limited experimental research on strengthened concrete or masonry specimens
  • finite element analysis of the strengthened components using the experiments either new or from the existing literature
  • seismic pushover analysis and performance-based evaluation

Outcomes

The expected outcomes for a VRES project is the documentation of:

  • the summary of the numerical approaches to model FRP-masonry and FRP-concrete bond failure
  • the merits and/or disadvantages of each approach in ability to model large deformations of the retrofitted structure
  • available experimental data on FRP strengthening of concrete and masonry buildings

The expected outcomes for Masters or PhD students are:

  • development of a performance-based framework for seismic retrofit of concrete or masonry structures

Skills and experience

Any student with structural engineering background is encouraged to apply.
